1 "Numbers dominate the world"-this peculiar view is the core of Pythagoras school's academic thought. Pythagoras School is a famous school that was active in the Greek city-states in the southern part of the Italian peninsula from the 6th century BC to the 5th century BC. This is a secret society composed of 300 noble youths, which conducts mathematical research and religious practice. The founder is the famous Pythagoras. They believe that numbers are the source of everything. Number is independent of the essence of things and the total root of everything. Because there are numbers, geometric points, lines, faces and a little solid. There are four elements, fire, water, air and earth, and solids, which constitute everything, so the number comes before things. The original state of the world is fire, which transforms into everything and everything into fire. However, this transformation relationship is measurable. When fire is transformed into everything, the form of fire has been extinguished and replaced by the form of air, water and earth. However, the principle of the nature of fire is eternal and still dominates the transformation between gas, water and soil. Heraclitus used it to express "the truth spoken" and believed that the correct truth expressed the real principle. As far as logos is the truth recognized by human beings, it can be understood as "reason" and "reason" As far as Logos is the origin of the world, it can be understood as "principle" and "law". First, Logos is the "world order" mentioned in the above quotation, which is manifested as a fire that burns to a certain extent and goes out to a certain extent. Secondly, the movement of fire, that is, the generation and destruction of all things, is perceptual, but it controls the logic that can feel the movement. His existence is neither a material thing nor a spiritual thing, but the most universal, abstract and generalized philosophical concept similar to essence. The proposition of the category of existence realized the transformation of Greek philosophy, marked the beginning of philosophical ontology, and directly influenced the formation and development of later philosophical thoughts. Empedocles believes that "water, air, fire and earth" are four basic elements. Earth, water and gas actually represent the solid, liquid and gas of matter, while fire represents color and temperature. He is convinced that these elements or essence are eternal, but their different combinations form a constantly changing and rich and diverse world. The motive force of uniting elements is "love", and the motive force of separating elements is "hate". He used the interaction of hate and love to explain the reasons for the change of the world, and on this basis, he established a set of circulation theory.
